摘要
为获得装药结构对ALP(主动式横向效应弹)横向效应的影响规律,采用有限元分析软件AUTODYN-2D对ALP以1 200 m/s着靶速度垂直侵彻4340钢靶板过程进行数值仿真研究。针对文中研究模型所得研究结果表明:与PELE相比,ALP可形成较大的穿孔直径和更好的横向效应。当炸药中心与弹底的距离与弹体高度之比δ/H为0.8、采用轴向环起爆和B炸药时,ALP横向效应最优。
In order to get the effect of charge structure on lateral efficiency of ALP（ active lateral penetrator） , numerical simulation of the process of penetrating 4340 steel target plate with ALP at 1 200 m/s was carried out by using finite element analysis software AUTODYN- 2D. The results show that compared with PELE, ALP can form a larger hole and has better lateral efficiency. When the ratio of distance between explosive center and penetrator bottom to the penetrator height δ/H is 0. 8, the ring initiation and explosive B are adopted, ALP shows best lateral efficiency.
